【JH-WWGX2 Submerged arc welding wires】
 


　　JH-WGX2是高強(qiáng)度埋弧焊絲，配合埋弧焊劑（特別是JH-SJ101，JH-SJ101G,JH-SJ101q等燒結(jié)焊劑）進(jìn)行埋弧焊接，熔敷金屬具有優(yōu)良的力學(xué)性能。
　　用途：配合JH-SJ101，JH-SJ101G,JH-SJ101q等燒結(jié)焊劑，主要用于焊接某些低合金鋼（如X70,X80,HG70,A70等）結(jié)構(gòu)，如果輸油管線和工程機(jī)械用鋼等埋弧焊接。熔敷金屬具有良好的低溫沖擊韌性和620~750MPa的抗拉強(qiáng)度。
 
　　焊絲化學(xué)成分：(%)



　　熔敷金屬力學(xué)性能(按GB/T 5293配合JH-SJ101)
